I love German stuff. That always gets me pumped. There's these guys called Schlechta Umgang with a song called Crew Song that always makes me feel like a bad ass.
I also like to hear old jazz and extremely cheesy stuff like Aqua. Then, when it gets really intense I'll play some hard rock like ACDC.
Anything that doesn't distract me with lyrics and has a really edgy sound tends to work for me
